摘要: 目的 探讨藏药蕨麻对实验性酒精肝损伤小鼠的保护作用。方法 50只小鼠随机分为5组:空白组,模型组,小、中、大剂量蕨麻组, 50 %酒精灌胃复制实验性酒精肝损伤模型,蕨麻每日2次 (50、100、200 g/kg),酒精每日1次(10 mL/kg),连续4周。小鼠最后1次给药4 h后,称重,眶静脉丛取血,离心取血清,全自动生化仪检测肝功指标[AST、ALT、碱性磷酸酶(ALP)];摘取肝脏称重,计算肝脏指数;剪取适量肝脏制成匀浆,检测肝脏组织中TG、TC、丙二醛(MDA)、脂质过氧化物(LPO)含量以及超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)、过氧化氢酶(CAT)活性;剩余肝脏10%甲醛固定后进行病理学检测。结果 小鼠酒精肝损伤后肝脏指数、AST、ALT、ALP明显升高(P<0.05);肝脏组织中TG、TC、MDA、LPO含量明显高于空白组(P<0.05);SOD、GSH-Px、CAT活性明显降低(P<0.05);病理学检测发现肝脏组织出现炎性浸润和脂肪空泡。蕨麻可明显改善这些现象,表现为降低肝脏指数和肝功指标(P<0.05),减少肝脏组织中TG、TC、MDA、LPO含量(P<0.05),增强SOD、GSH-Px和CAT活性(P<0.05),减少肝脏组织炎性浸润和脂肪空泡的产生。其中大剂量蕨麻的作用更加明显。结论 蕨麻可能通过减少自由基的产生,增强对自由基及其代谢产物的清除能力, 从而抑制脂质过氧化,起到对酒精性肝损伤的保护作用。

Abstract: AIM: To study the protection of Potentilla anserina on ethanol-induced liver damage in mice. METHODS: 50 mice were divided into 5 groups in random, and administered by gavage for 4 weeks. Potentilla anserina was given twice a day, ethanol once a day. When time limit arrived, mice were weighted, serum was afforded to detect liver function index, liver homogenate were prepared for biochemical detections, liver remained were fixed for pathological investigation.RESULTS: When mice damaged by ethanol, liver index, liver function index, contents of TG, TC, MDA and LPO increased distinctly(P<0.05), activities of SOD, GSH-Px and CAT decreased at the same time(P<0.05). Inflammatory infiltration and flat vacuoles were observed. Potentilla anserina ameliorated these changes evidently; the effects were dose-dependent. CONCLUSION: Protective effects of Potentilla anserina on ethanol-induced liver damage in mice were associated with antioxidation, enhancement of clearance of free radicals and metabolites, and inhibition of lipid overoxidation reactions.
